Xylooligosaccharides (XOS) are a type of prebiotic fiber that are composed of short chains of xylose molecules. Xylose is a simple sugar that is found in many plant-based foods, including fruits, vegetables, and grains.
In protein powders and other food products, XOS are often added as a dietary fiber to provide various health benefits. XOS are not digestible by humans, so they pass through the digestive system largely intact. However, they are fermented by beneficial bacteria in the gut, which can help to promote the growth of beneficial bacteria and support digestive health.
Studies have shown that XOS may have several potential health benefits, including improved digestive health, increased absorption of minerals such as calcium and magnesium, and improved immune function. They may also help to reduce inflammation in the body and improve glucose metabolism, making them potentially beneficial for individuals with type 2 diabetes.
XOS are generally considered safe for human consumption, and there are no known adverse effects associated with their use.
